## 1. Implementation Completed
### 🔒 Process-Level Sandbox (core/mcp-sandbox.js)
**What It Does**:
- Locks `process.env` (read-only, whitelisted variables only)
- Blocks `process.exit()`, `process.kill()`, `process.abort()`
- Blocks filesystem access (fs, fs/promises modules)
- Blocks shell execution (child_process, exec, spawn)
- Blocks dangerous module imports (39+ blocked modules)
- Freezes global objects (prevents prototype pollution)
- Prevents code execution (eval, Function constructor)
- Blocks network access (http, https, net, tls)
- Installs audit hooks for escape attempt tracking
- Verifies integrity before MCP server starts
**Code**:
- File: `core/mcp-sandbox.js`
- Lines: 240+
- Functions: 8 main functions
- Status: Complete and operational
### 🛠️ Tool Parameter Enforcement (core/tool-enforcement.js)
**What It Does**:
- Validates all tool parameters against strict schemas
- Checks required fields, types, values, extra fields
- Provides clear error messages to IDEs
- Audits all violations to trail
- Wraps all tool handlers with validation
**Schemas Defined** (13 tools):
1. `begin_session` — Mandatory session initialization
2. `read_file` — Read files
3. `read_prompt` — Read system prompts
4. `read_audit_log` — Access audit trail
5. `list_plans` — List approved plans
6. `replay_execution` — Forensic replay
7. `verify_workspace_integrity` — Verify logs
8. `generate_attestation_bundle` — Generate attestation
9. `verify_attestation_bundle` — Verify attestation
10. `export_attestation_bundle` — Export attestation
11. `write_file` — Write files (Windsurf-only)
12. `bootstrap_create_foundation_plan` — Create plans (Antigravity)
13. `lint_plan` — Validate plans (Antigravity)
**Code**:
- File: `core/tool-enforcement.js`
- Lines: 350+
- Schemas: 13 complete schemas
- Validators: Field-level + tool-level
- Status: Complete and operational
### 🎯 Server Integration (server.js)
**Changes**:
- Imported enforcement modules
- Installed enforcement layer at startup (before audit)
- Integrated `validateToolParameters()` into `validateToolInput()`
- Added enforcement validation step
- Proper error handling and logging
**Status**: Complete and operational
